TELEPHONE ATTACHMENT. p

Application filed July 5,

To all whom t may concern:

Be it known that I, Femmina) W. HoAN,

a citizen oi the United Statespresiding at New York city, in the county and State of 5 New York, have invented cer-tain newland useful Improvements in Telephone Attach ments, of which the following is a specificaf tion.

The present invention relates to receiver I holders for telephone instruments, the object beingto provide an exceedingly simple struc ture that will support the receiver at the ear of the user of the instrument, thus leaving both hands free. A further object is to provide a device in which the receiver is readily adjustable to different positions, so that it may be desirably located.

In the accompanying drawings:

Figure 1 is a side elevation of the attachment in a position to hold the usual hook down.

Figure 2 is a front view oi' the same,

Figure 3 is a side elevation with the receiver in position tor use, 25 Figure 4 is a detail perspective view of the ball and socket connection between the carrier arm and receiver bracket,

Figure 5 is a view in elevation oi' the supporting bracket,

Figures 6 and 7 are detail sectional views on the line 6-6 and 7 7 of Figure 2.

The usual desk telephone set is illustrated, the transmitter 8 being supported on a standard 9 and the receiver being designated 10.` The receiver-holding hook is shown at 11.

In the embodiment of the invention disclosed a supporting bracketk is employed, comprising a sectional collar 12 adapted to surround and be clamped about the standard 9 and having' an angular arm 13, the outer portion of which extends forwardly and upwardly. A carrier arm 14: is provided with a head 15, pivoted as shown at 16, to the tree end of the arm 13, and this carrier arm is adapted to swing between a position on the hook 11 and a position in advance of the receiver, as shown in Figure 3. v The head is provided with a circular periphery 1T broken by a notch 18 forming a stop shoulder 19. A leaf spring 20,I secured to the arm 13, has a curved terminal portion 21` that bears upon the curved portion 17 1921. Serial No. 482,446.

\ uosition as shown'in Fi ure 3.

Ihe carrier arm le terminates at its ree end in a ball -22 that is embraced and frictionally engaged by a pair otjaws 23, form ing a part of a` receiver supporting bracket. These jaws are mounted on a sectional ring 24 that surrounds the receiver 10. The jaws are drawn 1 toward each other by ascrew connection 25. Y

It will be evident that this device can be mounted on the usual telephone instrument and the ordinary receiver can be supported thereby. When so mounted the carrier arm 14 can be `swung to a rear position where it will rest upon the hook 11 and hold the same in depressed position. .When swung forwardly the spring rictionally rides onv the periphery 17 of the head 15, and thus atl'ordssome resistance to the movement of the arm, and the `foremost position of the arm and receiver is` determined by the shoulder 19 abutting against the free end of the spring. lin this position the receiver is located in convenient relation) to the lear of theuser of the telephone, the position of the receiver being readily variable in any direction by reason of the ball and socket mounting. Y p

From the foregoing, it is thought that the construction, operation and many advantages of the hereindescribed invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size,

shape, proportion and minor details of construction, may be resorted to without de-L parting from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A telephone attachment comprising a bracket member and means for mounting the same on a telephone instrument, a receiver carrying arm member pivoted to the bracket member and adapted to move between a position on the receiver hook and a position in advance of the same, one of said members 'I n v 1,530,897
